Maryland Boat Registration Calculator
Registration Cost Summary
What Is the Maryland Boat Registration Calculator?
The Maryland Boat Registration Calculator is a fee estimate tool for boat registration, titling, use stickers, and vessel excise tax in Maryland. It uses the values entered in the form to estimate the total amount due for a new registration, renewal, transfer, duplicate or replacement, or voluntary non-motorized registration.
This Maryland boat registration calculator adds the applicable fixed fees, calculates 5% vessel excise tax on the purchase price when the code applies it, caps that tax at $15,000, and adds late penalty and interest when a purchase date is more than 30 days past the tax due date.
The tool is useful for boat buyers, current owners, and people checking whether a vessel may qualify for an exemption. The final output is an estimated cost summary, not an official bill. It shows each fee line that applies and a total estimated fee amount.
How the Maryland Boat Registration Fee Formula Works
The calculator starts with fixed fee amounts stored in the code. The two-year registration fee is $70, the title fee is $20, the use sticker fee is $70, the voluntary non-motorized registration fee is $12, and the duplicate or replacement fee is $20. For new motorized or USCG-documented vessels with a purchase price above $0, it also calculates vessel excise tax.
Registration fee means the two-year vessel registration fee. Title fee applies only to new registrations and ownership transfers. Use sticker fee applies to motorized vessels and USCG-documented vessels when the vessel is not treated as exempt by the calculator. Excise tax applies only to new motorized or documented vessels with a purchase price above $0.
Late penalty applies only when a purchase date is entered and today is later than 30 days after that purchase date. The penalty is 10% of the excise tax. Late interest is 1.5% of the excise tax for each 30-day period, rounded up by month. Dollar outputs display with two decimal places.
Example: choose a motorized vessel, over 16 feet, over 7.5 HP, new registration, Maryland resident status, and a $25,000 purchase price. Leave exemptions unchecked and do not enter a late purchase date. The calculator adds $70 registration, $20 title, $70 use sticker, and $1,250 excise tax. The estimated total is $1,410.00.
Some edge cases change the result. A motorized vessel that is 16 feet or less with 7.5 HP or less gets a $0 registration fee, but still gets the use sticker fee. A nonresident under 90 days is treated as exempt. A voluntary non-motorized registration uses the $12 voluntary fee.

The result shows the fee lines that apply to your selections. It may show registration fee, title fee, use sticker fee, voluntary registration, duplicate fee, excise tax, late penalty and interest, and total estimated fees. The notes below the total explain why certain fees were added or waived.
What to Check Before You Calculate Maryland Boat Registration Fees
Small changes in the form can change the estimate. Before using the result, check the vessel type, registration type, exemption boxes, purchase price, and purchase date. These fields control most of the calculator’s logic.
Vessel type and exemptions
The calculator treats non-motorized vessels, certain out-of-state vessels, commercial USCG-documented vessels, government or municipal vessels, and emergency rescue boats as exempt when those boxes are checked. It also treats non-residents in Maryland under 90 days as exempt, even if the out-of-state exemption box is not checked.
Small motorized vessel rule
For a motorized vessel that is 16 feet or less and has 7.5 HP or less, the calculator sets the registration fee to $0. It still applies the use sticker fee when the vessel is otherwise not exempt. This is why a small vessel result may still show a total cost.
| Form Selection | How the Calculator Treats It |
|---|---|
| New motorized registration with purchase price | Adds title fee, use sticker fee, and 5% excise tax, plus registration fee unless the small vessel rule applies |
| Renewal for a motorized vessel | Adds registration fee and use sticker fee when not exempt |
| Transfer ownership | Adds title fee, plus applicable registration or sticker fees |
| Duplicate or replacement | Adds the $20 duplicate or replacement fee when not exempt |
| Voluntary non-motorized registration | Adds the $12 voluntary fee |
This calculator gives an estimate only. Actual Maryland boat registration costs can vary if the official rules, forms, fees, purchase details, exemption status, or agency review differ from the information entered. The tool does not replace guidance from the Maryland Department of Natural Resources or professional advice.

Is a non-motorized boat registration fee included?
A non-motorized voluntary registration fee is included only when selected. The calculator uses a $12 fee for voluntary non-motorized registration. It can be added through the non-motorized voluntary registration type or through the voluntary registration dropdown for a non-motorized vessel.
Does a USCG-documented vessel need a use sticker?
In this calculator, a USCG-documented vessel gets a $70 use sticker fee when it is not treated as exempt by the selected exemption boxes. For a new documented vessel with a purchase price above $0, the calculator can also add vessel excise tax.
How accurate is this Maryland boat registration fee estimate?
The estimate is only as accurate as the values entered and the fee rules built into the calculator. Real fees may vary due to official review, updated Maryland rules, purchase documentation, exemption status, or agency requirements. Use the result as a planning estimate, not a final bill.
